One of them is through the utilization of a gravitational lens. There are various techniques that astrophysicists are employing to find the distance of these galaxies. Hence, these discoveries are yet to be verified. If this is the case, we are witnessing these galaxies in their pre-Big Bang state.īut noted that it would take spectroscopic study, which divides an object's light into a spectrum, to verify the distances of these galaxies.

The record is currently being broken by a new wave of scientific discoveries, with some astronomers reporting the discovery of galaxies up to a redshift of 20. The further back in time we view a galaxy, the higher its redshift.Ī week after the first JWST science photos were made public, astronomers announced the discovery of galaxies at redshift 13 or roughly 300 million years after the Big Bang.

GN-z11, which scientists observed when it was around 420 million years after the Big Bang and had what astronomers refer to as a redshift of 11.6, was the most distant proven galaxy known before the JWST was deployed.Īccording to, redshift is a term used to express how much the universe has stretched the light coming from a galaxy.
